Abstract
The invention discloses a kind of foundation reinforcement method, it is related to the realm of building construction, the foundation reinforcement method makes slurries turn into the high-pressure jet of more than 20Mpa using high-tension apparatus, the impact failure soil body is ejected from nozzle, tiny earth material is allowed as slurries are emerged the water surface, remaining grogs injection stream impulsive force, under the effect such as centrifugal force and gravity, mix with slurries stirring, and puddled soil ratio in 2.5: 1 is regularly rearranged.An induration is formed in soil composite foundation is constituted together with inter-pile soil, so as to improve foundation bearing capacity, reduce the deformation of ground, reach the purpose of foundation stabilization.
Description
Technical field
The present invention relates to the realm of building construction, more for be related to a kind of foundation reinforcement method.
Background technology
Because people are to the development of building use requirement and the progress of Building technology, heavy duty industrial building, multilayer, high level
And Super High is civilian and public building increases increasingly, and the load of building is increasing, when subsoil can not meet
When supporting upper load and control building deformation, it is necessary to which ground is reinforced.Existing foundation reinforcement method is for sand
Or the subsoil effect of silt soil property is limited, it is impossible to enough increase substantially the steadiness of ground.
The content of the invention
Problem to be solved by this invention is to provide a kind of foundation reinforcement method.
To achieve these goals, the technical scheme taken of the present invention is:A kind of foundation reinforcement method, it is characterised in that
Comprise the following steps:
(1) drill:Actual conditions arrangement hole position according to ground, and drilled in cloth hole site using electric boring machine,
It is drilled into designed elevation;
(2) pipe is broken:Check that can seamless steel pipe ensure that slip casting is unobstructed, by several times by design requirement, seamless steel pipe is inserted to and is set
Meter elevation location, is inserted to the Grouting Pipe with nozzle in the precalculated position of soil layer;
(3) slip casting:After Grouting Pipe with nozzle is inserted to the precalculated position of soil layer, slurries are turned into high-tension apparatus
The high-pressure jet of more than 20Mpa, ejects the impact failure soil body from nozzle, allows tiny earth material as slurries emit water outlet
Face, remaining grogs under the effect such as centrifugal force and gravity, mixes in the impulsive force of injection stream with slurries stirring, and by 2.5: 1 slurry
Native ratio is regularly rearranged;
(4) divulge information:Slurries are blown using air blower, accelerate grout cures, formed in soil induration with
Inter-pile soil constitutes composite foundation together.
Beneficial effect:The foundation reinforcement method makes slurries turn into the high-pressure jet of more than 20Mpa using high-tension apparatus, from spray
The impact failure soil body is ejected in mouth, tiny earth material is allowed as slurries are emerged the water surface, impact of remaining grogs in injection stream
Under the effect such as power, centrifugal force and gravity, mix with slurries stirring, and puddled soil ratio in 2.5: 1 is regularly rearranged.
An induration is formed in soil composite foundation is constituted together with inter-pile soil, so as to improve foundation bearing capacity, reduce the deformation of ground,
Reach the purpose of foundation stabilization.
Specific embodiment
The following detailed description of a kind of preferred embodiment of foundation reinforcement method of the invention.
The foundation reinforcement method comprises the following steps:
(1) drill:Actual conditions arrangement hole position according to ground, and drilled in cloth hole site using electric boring machine,
It is drilled into designed elevation;
(2) pipe is broken:Check that can seamless steel pipe ensure that slip casting is unobstructed, by several times by design requirement, seamless steel pipe is inserted to and is set
Meter elevation location, is inserted to the Grouting Pipe with nozzle in the precalculated position of soil layer;
(3) slip casting:After Grouting Pipe with nozzle is inserted to the precalculated position of soil layer, slurries are turned into high-tension apparatus
The high-pressure jet of more than 20Mpa, ejects the impact failure soil body from nozzle, allows tiny earth material as slurries emit water outlet
Face, remaining grogs under the effect such as centrifugal force and gravity, mixes in the impulsive force of injection stream with slurries stirring, and by 2.5: 1 slurry
Native ratio is regularly rearranged;
(4) divulge information:Slurries are blown using air blower, accelerate grout cures, formed in soil induration with
Inter-pile soil constitutes composite foundation together.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and implementation method content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
Claims (1)
1. a kind of foundation reinforcement method, it is characterised in that comprise the following steps:
(1) drill:Actual conditions arrangement hole position according to ground, and drilled in cloth hole site using electric boring machine, it is drilled into
Designed elevation;
(2) pipe is broken:Check that can seamless steel pipe ensure that slip casting is unobstructed, by several times by design requirement, seamless steel pipe is inserted to design mark
High position, is inserted to the Grouting Pipe with nozzle in the precalculated position of soil layer;
(3) slip casting:After Grouting Pipe with nozzle is inserted to the precalculated position of soil layer, slurries are made to turn into 20Mpa with high-tension apparatus
More than high-pressure jet, the impact failure soil body is ejected from nozzle, allow tiny earth material as slurries are emerged the water surface, remaining
Grogs under the effect such as centrifugal force and gravity, mixes in the impulsive force of injection stream with slurries stirring, and in 2.5: 1 puddled soil ratio
Regularly rearrange;
(4) divulge information:Slurries are blown using air blower, accelerates grout cures, formation one is between induration and stake in soil
Soil constitutes composite foundation together.
